Advance EES Switch Back Up Alarm

Advance EES Switch Back Up Alarm

This is a genuine Terex backup alarm switch, also known as a reverse pressure switch. It is a critical safety component installed on the transmission, most commonly an Allison MT643, of a Terex Advance front discharge mixer. The switch is hydraulically actuated when the operator shifts the mixer into reverse, which closes the electrical circuit to operate the backup alarm and reverse lights. This part is a necessary replacement for malfunctioning or failed switches that cause intermittent or non-functional backup alarms and lights, ensuring the vehicle operates safely on a job site.
