Microswitch SNAP ACTION SPDT 0.1A 30VDC, model EB856145496

The Microswitch SNAP ACTION SPDT 0.1A 30VDC, model EB856145496 is a compact single-pole double-throw snap-action switch engineered for fast, reliable mechanical switching in low-current applications. It provides a distinct tactile snap operation that ensures quick contact changeover with minimal bounce, making it suitable for control circuits and small devices where precise on/off detection is needed. The small footprint and straightforward mounting options allow installation in confined assemblies and instrument housings.

Advantages

This microswitch offers a predictable snap action with clear tactile feedback and consistent contact travel, helping to reduce contact arcing and contact wear in low-voltage, low-current environments. Its SPDT contact configuration enables normally closed and normally open functions within a single device, simplifying wiring for changeover tasks. The compact design supports space-constrained layouts, while durable internal mechanics deliver repeatable performance over many cycles.

Suitable for

• Low-current control circuits and signal switching
• Instrumentation and measurement devices
• Small household or portable appliances
• Limit switches in compact mechanisms
• Prototyping and electronics projects requiring tactile switching

Key specifications

• Contact configuration: Single-pole double-throw (SPDT)
• Electrical rating: 0.1 A at 30 VDC
• Actuation type: Snap action for rapid contact changeover
• Physical form: Compact microswitch package suitable for confined spaces
• Typical applications: Low-voltage signal switching and control

How to use

Install the microswitch into the target assembly following the device’s mechanical mounting arrangement and ensure correct orientation for the intended actuator. Connect the common, normally closed and normally open terminals to the control circuit using appropriately sized wiring and secure terminations. Verify that the actuator or lever engages the switch travel within its designed operating range to ensure reliable snap action and contact changeover. Test the switch operation at the intended supply voltage and load to confirm correct behavior before final installation.

Usage recommendations

Use this SPDT snap-action microswitch in applications matching its low-current rating; avoid subjecting the contacts to higher currents or voltages than specified to prevent premature wear or failure. When used in environments prone to dust, moisture or vibration, consider protective enclosures or additional sealing measures. For reliable long-term performance, verify mounting stability and avoid mechanical overload of the actuator.
