Limit Switch SZL-WLC-B-N Woodworking Machinery Spare Parts Edebanding Machine Limit Switch

The SZL-WLC-B-N is a general purpose limit switch in the SZL-WL series, built as a spare for woodworking machinery including edgebanding machines. It carries an SPDT contact form, a roller lever actuator, a 10A current rating, and screw termination. Two things to confirm before ordering: that your machine's mount and lever reach match the roller lever, and that your circuit runs at or under the 10A rating. Send a photo of the old switch and its mounting position with your enquiry.

When a limit switch on an edgebanding machine stops tripping cleanly, the machine keeps running past its stop point or refuses to start the next cycle. A worn roller lever or a stuck contact leaves the control circuit reading the wrong position. Replacing the switch restores the stop signal the machine's sequence depends on.

This is a general purpose limit switch from the SZL-WL series, with SPDT contacts, a roller lever actuator, and screw terminals for wiring. It is rated 10A and sold as a spare for woodworking machinery. To confirm fit, compare the old switch's roller lever length and mounting hole spacing against this one, then trace which wire lands on common, normally open, and normally closed.

Check the lever's travel direction and the point where the roller meets the moving machine part. Mount the switch so the roller contacts the cam or dog squarely, not on its edge. With SPDT contacts and screw termination, you can wire to the normally open or normally closed side, so the stop signal works with your existing circuit logic.

Stock moves through DHL, FedEx, and UPS. No customisation or packaging options are stated. With your enquiry, send the machine make and model, a photo of the old switch in place, the wire count and which terminal each wire used, and the voltage and current your circuit switches.

What the specification fixes, and what it leaves to the machine:

• Roller lever tripping point — The roller lever rides against a cam or dog to trip the contacts, so the stop point is set by where the lever meets the moving part.
• SPDT contact wiring choice — SPDT contacts give one common, one normally open, and one normally closed terminal, so you can wire the stop signal either way.
• 10A current rating — Contacts are rated 10A, so match that figure against the current your control circuit actually switches before you order.
• Screw terminal connection — Screw termination lets you land each wire on its terminal with a screwdriver, which helps when swapping a switch on the machine.
• SZL-WL series fit — The switch belongs to the SZL-WL series, so check that the old unit carries the same series marking before you order a replacement.
• Edgebanding machine use — Sold as a spare for woodworking machinery, including edgebanding machines, where it signals position at a moving machine point.
• General purpose housing — A general purpose body suits control-panel and machine-frame mounting, so check the space around the old switch before fitting.

What changes on the shop floor when the right part goes back in:

• Restores the stop signal. A worn switch leaves the machine reading the wrong position, so the cycle runs past its stop. Fitting a replacement brings the stop signal back to the control circuit.
• Wire it either way. SPDT contacts mean the switch can feed a normally open or normally closed input. You match it to the circuit already on the machine instead of changing the logic.
• Match the circuit load. The 10A rating gives you a figure to check against your control circuit current. Confirm the circuit sits at or under it before the switch goes in.
• Screwdriver wiring on site. Screw terminals let each wire be landed and tightened with a screwdriver. That keeps the swap to a terminal-by-terminal job at the machine.
• One lever to inspect. The roller lever is the point that meets the cam, so wear shows up there first. Checking it tells you whether the switch or the cam is the problem.
• Series match first. The SZL-WL series marking on the old unit is the first thing to compare. A series match narrows the replacement before you look at the lever.

Check the old switch first. Compare its roller lever length, mounting hole spacing, and SZL-WL series marking against this unit, and send a photo of it in place with your machine model so the fit can be checked.

Mark each wire's terminal before you remove the old switch. This unit has SPDT contacts and screw terminals, so land common, normally open, and normally closed on the same points the old switch used.

It is the contact current rating. Check the current your control circuit switches and confirm it sits at or under 10A before fitting the switch.

It is the actuator that meets the cam or dog on the moving machine part. Mount the switch so the roller contacts that part squarely, not on the edge of the roller.

Shipment runs through DHL, FedEx, and UPS. Send your delivery address with the enquiry so the shipment method can be confirmed.

No customisation or packaging options are stated for this switch. Ask about your requirement in the enquiry and you will get a direct answer.

Send the machine make and model, a photo of the old switch in place, the wire count and which terminal each wire used, and the voltage and current your circuit switches.

Inspect the roller and lever for flat spots and check that the cam still meets the roller. If the lever looks sound, trace the wiring and the control circuit before ordering a replacement.
