The ZF Switches & Sensors GPTBLS01 is a heavy-duty snap action switch designed for reliable electrical switching in demanding applications. Manufactured in the US, this switch features a compact design with high current ratings and versatile terminal options, making it suitable for various industrial and electronic systems.
Key Features
Heavy-duty snap action mechanism for durability and long cycle life (tested to 1 million cycles)
Current switching capacity up to 20A at 125VAC / 250VAC
Wide variety of actuators for flexible installation
Screw or solder terminal options available in U.S. or metric sizes
Low operating forces for ease of actuation
UL rated for 125VAC and 250VAC applications
Constructed with phenolic case and cover, with silver alloy contacts for reliable conductivity
Note: The GP Series switches are available with screw or solder terminals in U.S. or metric sizes. For solder terminals, replace the “T” in the part number with an “S”. For metric mounting, replace the “1” in the seventh position with a “0”.
Specifications are subject to change without notice. Please refer to the datasheet for detailed technical information.
