Thumbwheel Switch

Guardian’s thumbwheel switch offers a mechanical life of 1.8 million cycles and ±1% independent linearity, with operation up to 30,000 feet. For mission-critical or fail-safe use, redundant circuitry is available to ensure highly reliable actuation. The unit can be custom-mounted to meet customer specifications.

High-performance industrial gear drive component for manufacturing applications.

Frequently Asked Questions

Yes. Select series use Guardian’s patented Triplex circuitry—three redundant switching circuits—with simplex/duplex options for critical or fail-safe applications.

Depends on series: up to 1.8 million cycles (thumbwheel), 1,000,000 cycles (pushbutton Triplex), and 50,000 cycles on several trigger/rocker variants.

Yes. Models include moisture-proof/dust-tight rockers and moisture-resistant/dust-tight MS-qualified 4-way switches for rugged environments.

Multiple power ratings across families; circuit options include SPST/SPDT (slide) and SPDT/DPDT (rocker). High-current options include trigger switches up to 10 A.

Yes. Several series support grip or panel integration, including multi-function display use (e.g., linear transducer; 5-way mini).
