Claims

[Scope of Claim for Utility Model Registration] 1. In a drive circuit for an anti-glare mirror using an electrochromic element, a switching circuit,
In a drive circuit having a control circuit and a changeover switch, the control circuit is configured to apply a coloring drive voltage only when the detected value of the terminal voltage of the electrochromic element during coloring is a value lower than the appropriate reference voltage of the ECD. 1. A drive circuit for an ECD anti-glare mirror, characterized in that it has a configuration consisting of a circuit in combination with a comparator circuit as shown in FIG. 2 The changeover switch has a lock contact for coloring and a momentary contact for coloring on the coloring side, a momentary contact for decoloring and a lock contact for decoloring on the decoloring side,
An ECD anti-glare mirror according to claim 1 of the utility model registration claim, characterized in that a dual-type 5-position changeover switch is provided, in which a neutral contact is disposed between a coloring side contact group and a coloring side contact group. drive circuit.
