The GPTBLS11 is a general-purpose snap action switch from the GP Series, designed for reliable switching applications with rugged construction and long operational life. It features a phenolic case and cover with gold over silver contacts, an operating force of 2.8 oz maximum, and a release force of 0.5 oz minimum, providing consistent and responsive switching performance. The switch has been mechanically life tested to over 20 million cycles and offers a current rating up to 20 amps at 250VAC (UL508 rating for GP*B series). With an ultra-small travel differential of 0.050 inches (1.27 mm), dielectric strength of 1000 VAC for 1 minute, and initial contact resistance of 15 milliohms maximum, this switch delivers reliable performance across a temperature range of 0°C to +55°C (UL) or -5°C to +40°C (VDE). The GPTBLS11 is commonly used in industrial control systems, appliances, and instrumentation where dependable snap action switching and long mechanical life are essential.
