APEM's 3500 series military style toggle switches feature molded-in terminal inserts and a silicone case seal that enables them to withstand 0.1 bar pressure under total immersion. These robust models also carry CECC contact ratings of 16 amps at 250 VAC and 15 amps at 32 VDC with a minimum life of 10,000 cycles. UL and CSA lists ratings up to 20 amps, 125 VAC, 3/4 HP, 15 amps, 250 VAC, 1.5 HP and T5, 115 VAC, 50/400 Hz for these high reliability models.

Single and double pole models are offered in an extensive range of single and double throw electrical configurations, including the popular ON-OFF, ON-ON, MOM OFF MOM, ON OFF MOM and ON OFF ON models. Other electricals include initial contact resistance of 10 milliohms maximum, insulation resistance of 1000 Mohms minimum and dielectric strength of 3000 V rms between terminals and frame.

The standard actuator is a chrome or nickel plated bat .238" diameter x .688" long, but 4 others are optional including a flatted style and one with a fluorescent tip for visibility under adverse glare conditions. Additional actuator finishes are available. An extensive offering of locking actuator styles is also optional for those critical safety applications where deliberate action is required to actuate the switch, or where positive resistance against excessive shock or vibration is essential.

The single pole body size is .591"w x 1.260"h x 1.236"d, while the double pole is .905"w with the same height and depth. Solder lug/quick-connect or screw terminals are optional. Superior quality engineering materials include silver cadmium oxide contacts and UL94-VO rated insulating material.

The 3500 series models will satisfy many critical switching applications in numerous industries where safety and high reliability are essential.
