The shaft is sealed to the bushing by an internal  
O-ring per MIL-P-5516B. The bushing is sealed  
to the panel with a silicone rubber washer and a  
stainless steel backing washer. The combined  
uncompressed thickness is 0.055" (1,40). Since  
this switch has a flat cover, a non-turn washer is  
supplied (see Panel Seal Kit). If using it, mount  
it in front of the panel.

Thus, with a 5 amp, 115 Vac resistive load,  
10,000 cycles of life is expected. If the load  
is reduced to 3 amps, life is increased to  
25,000 cycles. The larger angles of throw  
(45°, 60° or 90°) switch larger currents for a  
like number of cycles.

UL Recognition–  
Styles UA, UD, UM, UP, US and USP  
Grayhill styles ꢁ and M and their variations  
(ꢀ, P, S and SP) of the Series 42, 43, 44 and  
54 rotary switches have been tested by  
Underwriters Laboratories. The letter U in the  
style indicates proper marking as required by  
Underwriters Laboratories. These switches  
are recognized under file number E35289.  
The UL rating for the Series 42, 43, 44 and 54  
is as follows:
