Contacts Highly reliable contacts suitable for low level applications (10mA 50mV - 10A 5VDC min.) or power applications (2A 250VAC - 4A 125VAC - 4A 30VDC max.) Pinned lever The base of the switch lever is pinned to the bushing, thus earthing the lever to the bushing. This also provides strain relief to protect the switch if accidentally knocked. Double shell case For high mechanical strength and high electrical insulation. Compact size The small rear end of the switch allows space saving behind the panel. Finish Matt black finish on body, bushing, lever and hardware. Sealing Panel sealed to IP 67, these switches are frontal sealed by two O-rings and have full rear end sealing. Accessories A comprehensive range of protection boots (both full and half length), locking levers and security caps are available. www.apem.com APEMM3950/15 & M83731/23 QQPPLL lliisstteedd ttooggggllee sswwiittcchheess -- tthhrreeaaddeedd bbuusshhiinngg 1111,,99 ((1155//3322)) Specifications ELECTRICAL SPECIFICATIONS Max. current/voltage rating with resistive load : 2A 250VAC - 4A 125VAC - 4A 28VDC Minimum load : 10mA 50mV, 10A 5VDC When used above 300mA 28VDC, the gold plating is removed on contact areas and is considered only as a protection against oxidation during storage.
