Petercem G3 and T3 are two high-performance, hermetically sealed snap-action microswitches designed to meet extreme environmental requirements in aerospace, defense, and industrial applications. Both models are manufactured with stainless steel, inert gas-filled switch chambers and gold-plated silver contacts for maximum reliability in harsh conditions.

The G3 series features a compact design, flexible mounting and various actuator options, making it ideal for integration into confined spaces and customizable designs. It offers electrical capacity up to 5 A at 30 VDC and operates in temperatures from –55 °C to +150 °C, with a life cycle of up to 200,000 cycles.

The T3 series is designed for environments where high vibration and pressure resistance are critical. It is qualified to MIL-PRF-8805 and tested for helium leakage, ensuring absolute hermeticity. The T3 also handles up to 5 A at 28 VDC and offers the same wide temperature range and life as the G3.

Both the G3 and T3 are available with multiple mounting options, including flange, threaded bushing, and various cable exits (FL/FLL), making them reliable choices for applications where failure is not an option.
