The Minipress push button offers safe switching in the smallest of spaces under extreme conditions. The smallest push button in TSL’s range is based on a hermetically sealed, one-piece switch housing. It’s mechanical design guarantees a high level of durability regardless of temperature, dust or humidity. The MP push buttons can be customized by selecting different colors for the inside ring and LED lighting colors.

Despite its small construction type, this push button offers great functional reliability. For example, the Minipress Series offers a vibration-proof switching principle that prevents weather-related impulse emissions and blocking of the switching element. The Minipress is weatherproof, car-wash proof and resistant to conventional chemical cleaning agents. The MP push buttons are often used in trains, such as in high-speed trains in China, where there are often only narrow mounting plates.
