摘要： The present invention relates to a switch (1) for a switchgear, the switch comprising: a cylinder (20); a piston (30); a contact (50); a pin (60); and a stored energy unit (100). The piston is configured to move within the cylinder from a standby position to a released position along an axis of the cylinder. When in the standby position the piston is spaced from the contact and electrically isolated from the contact. When in the standby position the cylinder is electrically isolated from the contact. When in the released position the piston is in electrical connection with the contact. When in the released position the piston is in electrical connection with the cylinder. Movement of the piston from the standby position to the released position is configured to move the pin within a bore (53) of the contact from a standby position to a released position. Movement of the pin from the standby position to the released position is configured to indicate that the piston has moved from the standby position to the released position. The stored energy unit is located within or associated with the switch such that activation of the stored energy unit is configured to move the piston from the standby position to the released position.
