INGCO S-ID-SW-ID211002, Switch( S-ID-SW-ID211002)

product details:

The standard trigger switch is the workhorse of impact drills, providing control over on/off functionality, variable speed, and sometimes additional features. Here’s a deep dive into its components and functionalities:

Components:

• Housing: The housing is the exterior part of the switch, typically made of durable plastic for insulation and ergonomics. It comfortably fits your fingers for control.
• Trigger: This is the lever you squeeze to activate the drill. It’s usually made of a strong, wear-resistant plastic or composite material.
• Microswitches: These are small electrical switches inside the housing that activate different functions based on trigger position.
• Speed Control Mechanism: This can vary depending on the design. It might involve a simple pressure plate or a more complex cam system that adjusts motor speed based on trigger pressure.
• Terminals: These are electrical connectors that receive power from the battery or cord and send signals to the motor based on switch activation.

Functionalities:

1. On/Off: Squeezing the trigger compresses internal springs and activates microswitches. This completes the electrical circuit, sending power to the motor and turning the drill on. Releasing the trigger reverses this action, deactivating the microswitches, interrupting the circuit, and stopping the drill.

2. Variable Speed Control: As you squeeze the trigger further, a built-in mechanism (pressure plate or cam) within the switch housing increases pressure on a sensor. This sensor relays the change in pressure to the motor controller, which adjusts the motor’s speed accordingly. Harder squeezes result in higher speeds, while easing off the pressure reduces speed.
