Compact square momentary push button switch rated at 5A for 12VDC applications. Designed for automotive controls, electronic projects, control panels, and equipment circuits requiring reliable push-to-make operation and temporary circuit activation.
What it is
The E Auto Square Black Push Button Switch is a compact momentary control switch designed for automotive, electronic, industrial, and general-purpose switching applications. Featuring SPST-NO (Single Pole Single Throw – Normally Open) operation and Push-To-Make / Return-To-Break (PTM/RTB) functionality, the switch activates the circuit only while the button is pressed.
Its square panel-mount design provides a clean, professional appearance, making it ideal for dashboards, control panels, equipment enclosures, and custom electrical installations.
Use Cases / Applications
Suitable for a wide range of switching and control applications, including:
- Automotive control circuits
- Dashboard-mounted controls
- Electronic projects and DIY applications
- Control panels and switchboards
- Test and measurement equipment
- Industrial machinery controls
- Appliance controls
- Signal activation circuits
- Hobby and maker projects
- General-purpose momentary switching applications
Its compact design makes it particularly useful where panel space is limited.
Key Benefits
- Momentary Push-To-Make / Return-To-Break operation
- Compact square design for professional installations
- Reliable switching performance for control circuits
- Suitable for 12VDC, 125VAC, and 220VAC applications
- Easy solder-lug wiring connections
- Durable construction for everyday use
- Ideal for automotive, industrial, and electronic applications
- Cost-effective solution for control and signalling circuits
Momentary switches are widely used in electrical control systems because they activate a circuit only while pressed, making them ideal for triggering, signalling, testing, and temporary control functions.
Safety Compliance
- Rated 5A @ 12VDC
- Rated 0.05A @ 220VAC
- Suitable for low-voltage and low-current control circuits
- Install according to electrical safety requirements and applicable wiring regulations
- Ensure the connected load remains within the switch’s operating limits
Always isolate power before installation and verify circuit compatibility before use.
E Auto products are designed to provide dependable automotive and electrical switching solutions for replacement, maintenance, and custom installation applications.
Terminology:
Normally Open (NO):
A push button where the circuit is broken when the button is not pressed and closed (circuit connected) when pressed.
Normally Closed (NC):
A push button where the circuit is closed (circuit connected) when the button is not pressed and broken (circuit open) when pressed.
