The 5637MA is a single-pole toggle switch from APEM's 5000 series, featuring a momentary-off-momentary (MOM-OFF-MOM) contact function with solder lug terminals and a threaded bushing. It is rated for 4 A at 30 VDC maximum and 50 mA at 10 VDC minimum with silver contacts, with an initial contact resistance of 10 mO maximum and insulation resistance of 1000 MO minimum at 500 VDC. The switch exhibits a contact bounce of 2 ms maximum and is rated for 100,000 cycles of mechanical life or 50,000 cycles at full electrical load. It operates across a wide temperature range and is suitable for applications requiring reliable momentary switching in control panels, instrumentation, and industrial equipment where space is limited and durability is essential.
