Long Handle Mom. Switch

The Long Handle Mom. Switch from MOROSO is a heavy-duty momentary toggle switch designed for automotive and motorsport applications where reliable electrical control is essential. This starter-grade switch handles 20-amp loads at 12-volt systems, making it ideal for engine start circuits, fuel pumps, and auxiliary power distribution in custom builds, hot rods, and performance vehicles. The long-handle design provides ergonomic control and tactile feedback, ensuring confident operation even in high-vibration environments or when wearing gloves.

This momentary-contact toggle switch is engineered with robust electrical contacts rated for continuous 20-amp switching at 12 volts DC, delivering reliable performance in demanding automotive circuits. The extended handle reduces actuator stress and provides positive tactile engagement, critical for safety-critical functions like engine start or fuel system activation. Constructed to withstand vibration, temperature fluctuations, and repeated cycling, the switch meets the durability standards expected in professional racing and restoration work. Its compact form factor (3.7 x 1.55 x 5 inches) allows flexible mounting in tight engine bays or custom dashboard layouts without sacrificing accessibility.

Installers and fabricators building 12-volt systems will find this switch suitable for any momentary-contact application: starter buttons, ignition cutoff switches, fuel pump relays, or auxiliary lighting circuits. The 20-amp rating accommodates moderate-draw loads without thermal stress, though high-amperage applications should incorporate proper relay staging. Verify polarity during installation—momentary switches require correct positive and ground connections for safe operation. This switch pairs well with relay harnesses and fused circuits, ensuring system longevity and protection against electrical faults in custom and stock automotive platforms alike.
