LITTEL-SWITCH SWITCH WS SERIES 100, 100S, 200, 200S
LITTEL-SWITCH SWITCH WS SERIES 100, 100S, 200, 200S
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. Series 100S and 200S have 3 A
fine silver contact. 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" (6.35 mm)
thick in .375" (9.52 mm) diameter holes. Locknuts and
washers are supplied.
