The GPTCRM11 is a general purpose snap action switch designed for reliable switching applications with rugged construction and long operational life. It features a phenolic case and cover with gold over silver contacts, beryllium copper springs, and silver alloy contacts for durable switching performance. The switch has an operating force of 5.6 oz maximum, release force of 1.5 oz minimum, pretravel distance of 0.106 inches (2.70 mm), and operating point range of 1.17 to 1.21 inches (30.80 to 30.60 mm), with maximum overtravel of 0.094 inches (2.40 mm). Electrical specifications include 15A 250VAC rating per UL508, dielectric strength of 1000 VAC at 50/60 Hz for 1 minute, insulation resistance of 100 megohms minimum at 500 VDC, and initial contact resistance of 15 milliohms maximum. The switch operates over a temperature range of 0°C to +55°C (UL) or -5°C to +40°C (VDE), with US-style mounting holes (#6-32 fastener at 6.0 In-Lb maximum torque) and screw terminals made of brass. This switch is ideal for industrial control panels, appliances, and automation equipment where reliable snap action switching and long mechanical life are essential.
