What type of switch controls the air pump?

The type of switch that controls the air pump is a three-position lever switch that is pneumatically controlled. This design allows for more nuanced control over the air pump's operation, as it can offer features such as 'Off', 'On', and 'Auto' or similar settings, depending on the specific needs of the system.

Pneumatic control is often utilized in environments like fire rescue, where reliability and the ability to manage complex systems are crucial. The three-position lever switch provides a tactile user interface that is intuitive for operators, allowing them to easily understand the status of the air pump and adjust it as necessary during operations. This ability to manage the air pump in different states enhances efficiency and ensures proper use of the equipment.

Other types of switches like the two-position toggle switch, rotary dial switch, or single-position push button have limitations in this context. A two-position toggle switch would only allow for on/off operation, lacking the versatility that the three-position lever switch offers. A rotary dial switch is typically used for settings that require continuous adjustment rather than distinct operational states. Similarly, a single-position push button would only activate the air pump momentarily, which would be inadequate for ongoing pump operations crucial in emergency scenarios. Hence, the three-position lever
