The new IA Series of pushbutton switches from APEM are recommended for applications requiring protection from dust, sand, water and other contaminants. The actuator consists of a polyurethane membrane which depresses when the switch is actuated. The membrane is press fitted onto the bushing, providing an IP67 front of panel seal and ensuring high resistance to frost and external contaminants. Potential applications include off road vehicles, farm equipment, machine tools, food processing equipment and medical instrumentation. The actuator material provides a soft feel and allows easy operation even with gloved hands. The low profile design allows easy actuation when the switches are matrix mounted. Specifications Include: Bushing diameter: 16 mm Minimum pitch for matrix mounting: 20 x 20 mm Operation force: 6.5 N Electrical functions : momentary NO or NC/NO Current/voltage rating: 2A 24VDC Contacts: silver Electrical life: 1 million cycles Operating temperature: -20°C to +65°C
