Switch

1. Overview

A simple voltage controlled switch. The resistance ($R$) varies linearly when the control voltage ($V$) is between these thresholds:

$$R = R_L + \frac{(R_H-R_L)}{(V_H-V_L)} * (V-V_L)$$

where:

• $V_H$ is the upper threshold voltage
• $V_L$ is the lower threshold voltage
• $R_L$ output resistance when on
• $R_H$ output resistance when off

When the control voltage is greater than $V_H$ the switch has resistance equal to $R_L$. When the control voltage is less than $V_L$ the switch has resistance equal to $R_H$.

note

The upper threshold must be higher than the lower threshold.
