Honeywell HD Snap Action and HD1 Slow Action Basic Subminiature Microswitches are small footprint (HD1) and cost-effective (HD) switching solutions that assist in hitting overall system-level size and design goals in high-volume applications. Honeywell HD1 switches provide a slow-action mechanism that enables a compact switch footprint and design. HD switches offer value-add (wiring, molding, and connectors) for plug-and-play switch solutions. HD and HD1 Microswitches are ideal for use in presence detection and operator controls or as flow switches, power switches, and pressure switches.
