The APEM 637H/2-5 is a compact panel-mount toggle switch from APEM's standard industrial switch line, featuring momentary (On)-Off-(On) operation for applications requiring spring-return functionality. Installation requires a 12.2mm panel cutout with solder-terminal back connection. Critical verification: confirm 5A @ 25V dc rating matches the control circuit load to prevent contact degradation.
