Momentary Switch

A momentary switch activates a circuit only when held in the closed position, shutting off when released. The momentary switch provides temporary power control, which is different from the sustained on-off positions of latching switches. Waterproof sealing and low-voltage compatibility expand a momentary switch's utility for industrial controls, vehicle accessories, and more applications needing compact push-button power activation.

Standard functions of a momentary switch

Momentary switches deliver fingertip power control. Ideal for functions needing power only when actuated, push button momentary switch models deliver pulses of current flow when engaged. The momentary switch avoids having to manually turn a standard toggle on and then off again. Common examples include engine start buttons and pedestrian crosswalk call switches. A momentary switch simplifies temporary power delivery for a more efficient process.

Momentary switch options that are rated for voltages from 5 to 48V DC suit automotive and low-voltage systems. The low-voltage contacts of a momentary switch prevent dangerous sparking or erosion at contact separation found in 120 to 240VAC switches. Meanwhile, 12V momentary switch models safely operate wiper and winch controls on vehicles. DC-rated momentary switch models can perform reliably despite any voltage transients. With temporary activation and heavy-duty construction, low voltage momentary switch options provide convenient push-button power delivery and control that are ideal for industrial equipment, machinery, and automotive accessories.

Special features of a momentary switch

Full encapsulation of contacts and connections enables waterproof momentary switch options to withstand wet conditions, weather, and high-pressure washdowns. The waterproof durability of a momentary switch makes it ideal for outdoor applications like gate controls, car wash tunnel controls, and marine equipment. Waterproofing provides remarkable long-term resilience for more durable momentary switch quality in the years to come. Waterproofing and low-voltage momentary switch models effectively expand utility across various settings, from manufacturing to marine industries.

Exceeding standard snap-action switches, a 12 volt momentary switch provides elevated contact forces up to a thousand grams. The momentary switch allows users to control high-inrush inductive loads like motors or lamps with fast transition times and minimal arcing. Also, the strong contact forces that the momentary switch offers prevent contact failures under heavy loads.

Many momentary switch options incorporate colored LED illumination for user feedback. LEDs activating when engaged confirm a momentary switch's function and help locate switches. The illuminated momentary switch models also feature backlit labels for better visibility in low-light conditions. User feedback input improves a momentary switch's overall usability and function confirmation.
