*Measured above reference line. Refer to dimensional drawing above. **Actuator tolerance ± 0.031 inches (0.79mm).
Only available with 85°C temperature rating.
Note: E35 and E36 not available in standard force. See Miniature E Series Light Force for ordering information. Suffix numbers shown represent
switch with 0.187
″ (4.75mm) terminals.
Specifications subject to change without notice.
Dimensions — Standard Force inches (mm)
Part Number Suffix –50N
Part Number Suffix –90N
Mounting — Standard Force
Recommended mounting screw size:
#4-40 round head. Recommended torque
on screw: 3 inch lbs. max.
Ordering Information
Select the current rating you need.
Combine the corresponding Series/Prefix
number with the appropriate suffix number
for the switch type, circuitry and terminals
you require.
Circuitry — Standard Force
Contact arrangement available in choice of
single pole double throw or single pole single
throw, either normally open or normally
closed. In general normally open may be
specified by changing suffix number from
00 to 01 and normally closed by changing
suffix number to 02.
