ROUND MOMENTARY PUSHBUTTON SWITCHES
100, 200 SERIES OPEN FRAME, REAR MOUNT, .375 MOUNTING HOLE
1. 101
2. 102
3. 103
Momentary switches feature leaf springs, insulating spacers, notched insulating washers and plated copper alloy bushing assembled into a rugged, reliable, long-life switch for limited space applications. Series 100 and 200 have integral .25 A contacts intended for low power switching where contact resistance is not critical.
Red and black pushbuttons, solder lug terminals and choice of 1-A, 1-B or 1-C switching are standard.
Shaft and pushbutton molded as one piece. Captive shaft extends through bushing, actuated leaf springs. Notched phenolic washers insulate springs and interlock all members, eliminating possibility of springs shifting. All springs are insulated from bushing.
MOUNTING
Switches mount from rear in panels up to .250 inch (6.35 mm) thick in .375 inch (9.52 mm) diameter holes. Locknuts and washers are supplied.
