## Abstract

Electrical switching has been observed in methyltriphenylarsonium-$(TCNQ)_2$ (7,7,8,8-tetracyanoquinodimethane) at different pressures up to 8 GPa at a temperature of 300 K. At high fields $\sim{3}\times{10^3}$ V/cm, the sample switches from an off state of several k$\Omega$ resistance to low resistance on state of several ohms. Pulsed current-voltage characteristics reveal heating contribution to nonohmic conduction and switching. The switching time recorded is 0.5 ms. Nonohmic conduction is discussed in terms of space charge limited currents possibly leading to a structural phase transition.
