What position is a push-to-break switch usually in?

A push-to-break switch is typically designed to be in the "on" position when not actively engaged. This means that when the switch is not being pressed, the circuit remains closed, allowing current to flow. When the switch is pressed, it breaks the circuit and stops the current, hence the name "push-to-break." This is commonly used in situations where a temporary interruption in a circuit is needed without having to manually switch it off and on repeatedly. It provides a straightforward way to control power and is often used in applications where immediate cessation of power is required upon pressing the switch.

In contrast, if the switch were in the "off" position, it would not allow any current to flow, rendering it ineffective for its intended purpose. The "emergency mode only" option implies a specific condition that does not reflect the normal operational state of a push-to-break switch. "Half power" does not accurately describe the state of a push-to-break switch, as it operates in a binary manner of either allowing current to flow or breaking the circuit entirely.
